Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...

Termination resistors and the ratio units of voltage and power — dB — are interrelated topics. The dB units can refer to voltage or power, and conversions between voltage dB units and power dB units ...

International technical platforms such as the IEEE PES Transmission & Distribution Conference and Exposition play a key role in shaping these developments by bringing together grid operators, ...

A close collaboration with major transformer manufacturers has lead to the new Tettex 2796 Transformer Turns Ratio Meter. It combines mobility and user friendly handling with unmatched accuracy of up ...

TT electronics BI Technologies Electronic Components Division has expanded its line of thin film resistor networks. Designated the SS1 Series, the networks consist of two ultra-stable Nichrome thin ...

The first case study is about an on-site measurement on a 66kV to 132kV reference VT. The secondary winding has two taps for adapting the voltage ratio between 132kV/√3:110V/√3 and 66kV/√3:110V/√3.
